To all whom it may concern: I

Be it known that I, GEORGE HoLLnN- BECK, a citizen of the United States, residing at Levering, in the county of Emmet and State of Michigan, have invented certain new and useful Improvements in Heating-Stoves, of which the following is a specification.

This invention relates to improvements in heating stoves, more particularly to de vices of this character employed for burning special forms of fuel, and has for one of its objects to simplify and improve the construction and increase the efliciency and utility of devices of this character.

With these and other objects in view, the invention consists in certain novel features of construction, as hereinafter shown and described and then Specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention Figure 1 is a vertical sectional elevation of the improved device; Fig. 2 is a transverse section on the line 22 of Fig. 1; Fig. 3 is a transverse section on the line 33 of Fig. 1; Fig. & is an elevation, partly in section, illustrating a modification in a portion of the construction.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved device comprises a hollow base, represented as a whole at 10, preferably elongated and with a draft door 11 at one end, a relatively large opening, indicated at 12, in the top, preferably near the door 11, and a plurality of relatively small openings 13 in the top near the other end. The door 11 is provided with a perforated damper 11 having alternating apertures and imperforate portions of the usual form and pivoted at 11 to the door to control the inlet of air. Supported upon the base 10 is a fire pot comprising a cylindrical upper portion 14: having a flange 15 engaging in the opening 12 and a conical lower portion 16 resting by its upper rim upon the flange 15, the discharge of the portion 16 being somewhatcontracted, as shown at 17 and extending for a short distance into the interior of the base 10, A fuel magazine 18 engages at its lower end over the portion 14; of the fire pot-and rises for a considerable distance above the same. A top member, represented as a whole at 19, bears upon the upper end of the magazine 18 and is provided with a relatively large opening 20 which communicates with the magazine. A closure 21 is disposed upon the member 19 and over the opening 20 and is pivoted at 22 at one side to the top member 19 so that the closure may swing laterally to uncover the opening 20 and permit the insertion of the fuel into the magazine. The top member 19 is provided with a plurality of openings 23 which are arranged in vertical alinement above the openings 13 of the base 10. Each of the openings 13 and23 are provided with retaining flanges to receive the terminals of a plurality of fines 2%, six being shown for the purpose of illustration. Bearing upon the top member 19 is a hoodlike device which covers the openings 23 and is bolted or otherwise secured to the top 19, as shown at- 26. The hood member 25 is provided with an opening 27 in its upper side and surrounded by a flange to support the main smoke flue 28.

Disposed within the base 10 and below the fire pot is a grate device, represented as a whole at 29, and extending from side to side of the interior of the base. The grate device is mounted upon journals or trun nions, indicated at 30, and held from movement in one direction by stops 29 and adapted to be tilted or shaken vertically in one direction. At its center the grate device is provided with a plurality of radial openings, indicated at 31, and mounted for rotation by a pivot 32 is a draft controlling element, indicated as a whole at 33, and provided with a plurality of radial openings 34 corresponding to and adapted to register with the openings 31 of the grate device when the member 33 is in one position. The openings 31 are separated by imperforate portions corresponding in size therewith, while the openings 31 of the draft controlling element will likewise have imperforate portions corresponding in size with the openings. By this arrangement it will be obvious that when the member 33 is disposed in one position the solid portions between the openings 34 will close the openings 31, and when the member 33 is rotated in either direction the openings will be caused to register to a greater or less extent. By this means the sizes of the openings may be readily controlled by simply actuating the member 33. Projecting from the member 33 at one side is an operating arm 35 to which a suitable implement may be applied when'the door 11 is opened to enable the member 33 to be actuated.

Extending transversely of the interior of the base 10 are plates 45, the latter being spaced apart and arranged in step like order, as shown in Fig. 1. By this means the fuel or other material passing over the grate device will likewise pass over the members l5 and be subjected to the action of the air passing between the members 4-5 and the grate device. Then the damper 11 of the door 11 is opened the air will pass both above and below the grate device and through the spaces between the members and thus supply the fuel with the necessary air. Arranged within the interior of the magazine 18 are means for controlling the flow of the fuel. In Fig. l the controlling means consists of a plurality of reversely arranged inclined plates or retarders 36, while in Fig. 4 the retarding element is in the form of a screw conveyer comprising a central shaft 37 having the floats or wings 38 of the usual form. At its upper end the shaft 37 extends through an opening in a transverse bar 39 in the opening 20 and is formed square at its upper end to receive an operating wrench or like implement. At its lower end the shaft 37 is stepped in a transverse bar il carried by the lower portion 16 of the fire pot. The slope of the floats or wings 38 will be sufficient to permit the fuel to flow slowly thereover, and if a more rapid flow is desired it can be produced by simply rotating the shaft 37. By this means the How of the fuel may be readily controlled as requiret. An opening 4:6 is formed in the portion 16 of the fire pot and covered by a swinging door 47 to provide an observation opening.

Having thus described the invention, what is claimed as new is 1-- 1. In a stove, a. hollow base, a fuel magazine rising from the base, a smoke conveying element communicating with the base, a fire pot at the juncture of the fuel magazine and the base, a grate below the fire pot, a draft controlling element coactlng with the grate, and a plurality of feed elements spaced apart Copies of this patent may be obtained for and arranged in inclined steps andadapted to receive the fuel passing from the grate.

2. In a stove, a hollow base, a fuel magazine rising from the base, a smoke conveying element communicating with the base, a fire pot at the juncture of the fuel magazine and the base, a grate below the fire pot, a draft controlling element movably engaging the grate, and a plurality of feed elements spaced apart and arranged in inclined steps and adapted to receive the fuel pass ing from the grate.

3. In a stove, a hollow base, a fuel magazine rising from the base, a smoke conveying element communicating with the base, a fire pot at the juncture of the fuel magazine and the base, a grate below the fire pot, a draft controlling element coacting with the grate, a plurality of feed elements spaced apart and arranged in inclined steps and adapted to receive the fuel passing from the grate, and means for supplying air over and beneath the grate.

at. In a stove, a'hollow base, a fuel magazine rising from the base, means within the magazine for controlling the How of the fuel therethrough, a smoke conveying element communicating with the base, a fire pot at the juncture of the fuel magazine and the base, a grate below the fire pot, a draft controlling element coacting with the grate, and a plurality of feed elements spaced apart and arranged in inclined steps and adapted to receive the fuel passing from the grate.

5. In a stove, a hollow base, a fuel magazine rising from the base, a conveyor element within the magazine and operating to force the fuel therethrough, a-smoke conveying element communicating with the base, a fire pot at the juncture of the fuel magazine and the base, a grate below the fire pot, a draft controlling elementcoacting with the grate, and a plurality of feed elements spaced apart and arranged in inclined steps and adapted to receive the fuel passing from i the grate.
